MOSCOW: Russian lawmakers on Tuesday announced plans to push through legislation introducing harsher punishments for those who carry out deadly attacks, as Russia tightens security ahead of February’s Winter Olympic Games in Sochi. A cross-party group of lawmakers will submit three draft bills to parliament on Wednesday, Irina Yarovaya, a ruling party lawmaker and the head of the Duma’s security and anti-corruption committee, told the Interfax news agency. The legislation will introduce sentences of up to 20 years or even life sentences for “organizing and committing crimes of a terrorist nature and for organizing financial terrorism,” she said.
